I trimmed the trunk because it was growing quite tall and spindly. Is there any way to continue growing the main trunk or will it only grow branches now?

If you cut the top off then it will only be able to grow branches at this point.
Darn, will the trunk grow any taller or is that it?
The main trunk will stay the same height at this point, but it will get thicker as it matures. Your best bet is to encourage a few branches out and go for a wine glass shape off the main trunk. With some pruning you can make it look like a pretty nice dwarf tree!
They are easy to grow. Just toss another seed in the dirt beside it.
You could try grafting it. It’s been a while since I last grew avocado plants, but I would graft them, especially because it will help them produce fruits later on.
